Senior Software Engineer (Backend/Fullstack)

Do you want to work with the cutting edge of medical diagnostics, saving millions of lives, while working with some of the smartest people in the industry? BillionToOne (Y Combinator S17) is looking for a Senior Software Engineer. We’ve built the most accurate cell-free DNA test for pregnant mothers by applying bioengineering and machine learning principles to state of the art molecular testing. Our QCT platform improves resolution of cell-free DNA testing by >1000x fold and enables novel tests for both prenatal and oncology care. Projects you may work on include: bioinformatics data processing pipelines, laboratory automation tools, and web-based tools to communicate genetic results to patients. This is a highly impactful position with the opportunity to own engineering end-to-end from internal prototypes to widely deployed products directly affecting patients.

If you have experience in full life-cycle development, love seeing your work positively affect your colleagues, and thrive in a fast-paced entrepreneurial environment, this could be a great opportunity for you.

Projects you may work on include:

• Develop a secure portal for physicians and patients to access the results of genetic tests
• Expand tooling for the Clinical and Operations team by integrating the internal BillionToOne API with external data sources (e.g. logistics, medical records, sales and marketing).
• Work with the R&D and process engineering for robotics-related laboratory automation
• Semi-automate data entry tasks via a pragmatic combination of OCR and UI/UX engineering

Technologies we use include Django / Django rest framework, Python, Postgres, AWS: s3, ECR, ECS, Heroku, R

Requirements

Who You Are:

• 4+ years as a software engineer
• You prefer and specialize in Back End development, but you’re also productive working on the Front End when needed.

More About Us:

BillionToOne has developed a DNA molecular counter that increases the cell-free DNA diagnostics resolution by over 1,000 fold. We are the only technology platform that can detect single-gene disorders in an unborn baby from maternal blood and that can accurately quantify copy number variation (CNV) changes in cancer patients. Our first product, UNITY, is the only NIPT that accurately detects single gene disorders such as cystic fibrosis and sickle cell in the baby from a blood test of the mother. UNITY covers all inherited disorders that every pregnancy needs to be tested for and has 98.5%+ sensitivity and 99%+ specificity.

BillionToOne has recently raised a large Series B funding from global institutional investors, including from Hummingbird Ventures, NeoTribe Ventures and Y Combinator:
